About chimney repairs & repointing

The chimney stack takes more weather than any other part of a house, and on older properties it's usually the first thing to fail: frost-shattered bricks, crumbling mortar joints, cracked flaunching around the pots, and leaks where the lead flashing meets the roof. Chimney specialists in our network handle repointing in the correct mortar mix (critical on older brick), partial and full rebuilds, capping and cowls for disused flues, flaunching repairs, and renewing the lead aprons, soakers and back gutters where most chimney leaks actually start.

How we help

Find Trusted Roofers is a national network that connects UK homeowners with local roofers. We are not a roofing contractor and we don't do the work ourselves — instead, you tell us about your chimney repairs job once, and we match you with a roofer in our network who covers your postcode and works on your roof type. Every roofer quotes from their own survey; you deal directly with them and choose whether to proceed.

We check the roofers in our network against Companies House, confirm public liability insurance, and note any TrustMark, NFRC or CompetentRoofer membership. We verify what we can — we don't guarantee the work, which is contracted directly between you and the roofer.

Available across the UK

We connect homeowners with local roofers offering chimney repairs in towns and cities across England, Scotland, Wales and Northern Ireland. Browse areas we cover.

Chimney Repairs & Repointing — FAQs

How much does chimney repointing cost?
Repointing a typical stack costs around £400–£1,000 depending on height, access and whether scaffolding or a tower is needed. Access is often half the cost of any chimney job, so combining chimney work with other roof repairs saves money.
Why is water coming in around my chimney?
The most common causes are failed lead flashing where the stack meets the tiles, cracked flaunching on top of the stack, and porous or frost-damaged brickwork absorbing water. Each has a different fix, which is why proper diagnosis matters more than a quick smear of sealant.
Should I cap a chimney I don't use?
Yes — a capped, ventilated flue keeps rain and birds out while letting the stack breathe. Sealing a flue completely with no ventilation traps moisture and causes damp inside the chimney breast.
Can my chimney be repaired, or does it need rebuilding?
If the brick faces are spalled (blown) or the stack leans, a partial rebuild from the roofline up is often the durable answer. If the bricks are sound and only the joints have weathered, repointing does the job at a fraction of the cost.
Do you need scaffolding for chimney work?
Usually yes — either a scaffold tower or a purpose-built chimney scaffold. It's a legal safety requirement for most stack work and will be itemised on any honest quote.
